SSL Certificate Glossary of Terms: S
A Web server that utilizes security protocols like Secure sockets layer (SSL) to encrypt and decrypt data, and messages. Security protocols protect them against fraud, false identification, or third party tampering. Purchasing from a secure server ensures that a user's credit card information or other personal information is encrypted during its passage over the internet to the merchant's server. Popular security protocols include SSL, HTTPS, SSH2, SFTP, PCT, and IPSec.
An Internet protocol which uses encryption to supply data confidentially, providing privacy and data integrity amid a client and a server transaction. SSL HTTP can also, as an option, provide peer entity authentication amid the client and the server with secure SSL validation of Digital Certificate. SSL is layered below HTTP and above a transport protocol (TCP). SSL is independent of the application it summarizes and any other higher-level protocol can layer on top of SSL transparently. SSL has two layers: (a) SSL's lower layer, the SSL Record Protocol, coated on top of the transport protocol and encapsulating higher level protocols. (b) SSL's upper layer, supplying asymmetric cryptography for server authentication, which is verifying the secure server's digital identity to the client with digital ID signatures or certificates. Te process of verifying the client's identity to the server is known as client authentication. It also allows them to negotiate a symmetric encryption algorithm and secret session key, used for data confidentiality, prior to the transmission or receiving of data by the application protocol. A keyed hash offers data integrity service for data that is encapsulated. See also Transport Layer Security (TLS)
A state in which no subject can get access into any object in a manner that is illicit. SSL Certificates provide a Secure State.
(a) A relationship established among two or more entities to allow them to guard data they swap. The relationship negotiates characteristics of defense mechanisms but does not involve the mechanisms. (b) Used in IPsec as a simplex (unidirectional) logical connection generated for purposes of security and put in with either ah or esp, but never both. The security association offers security services that depend on the protocol chosen, the IPsec mode transport or VPN tunnel, the endpoints and the choice of optional services in the SSL protocol. A security association is recognized by (a) a destination IP address, (b) a protocol identifier or (c) a security parameter index.
A self-assessing review and investigation of a system's policy, records, and actions to determine the capability of system controls, guarantee compliance with conventional security policy and processes, discover breach in security services, and recommend any alterations which imply a need for countermeasures. The objective of the basic audit is to establish accountability for systems which initiate or participate in security-relevant occurrences and actions. Means are needed to create and record security audit information and are also need in order to review and analyze the audit trail in order to detect and exam attacks and compromises of security.
A term used, more often than not negatively, in reference to the procedure of attempting to secure a system for Internet security and online security by failing to publish any information about it. This is done in the hope that no one will figure out how it works.
The security mechanisms where proper functioning is required in order to make sure that the security policy is actually enforced.
An evaluation assessing the level of trust or assurance which can be placed in systems for the secure management of sensitive information. One sort, a product evaluation, is an assessment of the hardware and software features and promises of the computer product, leaving out the application perspective. A different kind, a system evaluation, is performed to gauge a system's safeguards with respect to an explicit operational mission. This is an important step in the certification and accreditation process for strong authentication and secure SSL authentication that supplies online Internet security with Digital Certificate.
An analysis, more often than not performed on hardware at the gate level, to determine the security properties of an apparatus when a hardware fault occurs.
These are a compartment of system security safeguards used for online security (SSL digital certificates for example)
A dependable subsystem enforcing a security policy on the data that passes through it.
This is an error of commission or omission in a system which may falsely permit secure mechanisms or safeguards to be bypassed, weakening internet security.
The hardware, firmware, and software components of a tcb which use the concept of reference monitor. Secure kernels have to mediate each and every access, be guarded from modification, and be provable to be effective.
This is the amalgamation of a hierarchical classification and a group of non-hierarchical categories representing information's sensitivity.
These are the constituents of software, firmware, hardware or processes which are included in a system for the approval of security expectations or security policy. They are used for Internet security to prevent unauthorized intrusion with 128-bit digital certificates with secure SSL authentication.
Signature is a unique and distinct pattern that is used to detect a virus infection or system penetration (see intrusion detection system), or as a "Digital ID" for SSL secure systems. The digital signature can be a permanently-set string of bytes, or it can be more complex and algorithmically-based, as with a secure socket layer. ID Signatures for secure server system penetration are by and large much more complex. They can even include the comparison of many different types of data in a security audit with logging.
Single sign-on is a system, process or procedure in which a user is authenticated on one occasion, giving them access to a lot of disparate systems from that time on. It is like secure authentication or secure SSL authentication that only has to be done a single time.
Super-User is a user with full, unlimited and unrestricted access to each and every portion and resource of the system, such as the PKI Manager who administers and manages SSL Certificate duties on a large network.
Private key encryption, or "symmetric key encryption" uses the exact same, private key for both encryption and decryption. Both parties share the key as the factor for the communication. Symmetric key systems do not have to have a public key infrastructure (PKI) the way that asymmetric key encryption has to. Symmetric key encryption requires a secure channel for key exchange, unlike other kinds of 128-bit encryption with SSL.
The condition an SSL secure server is in when it executes its intended operation in an unimpaired manner, free from advertent or inadvertent unauthorized manipulation of the system.
